Spiral chute is an experienced and scientific product which is the best concentrating equipment especially for concentrating the sand. The advantages include reasonable structure, simple installation, small size, easy operation, even concentration, clear separation, high efficiency. The product is made of the chlorine plastic, so that it is properly suitable for the changing of th feeding size, granularity and grade.

During use of the chute, heavy ore particles can move to the inside of the chute from the outside under low resistance due to the fact that the upper surfaces of the steps are inclined inward, lateral vertical surfaces of the steps can stop and prevent the heavy ore particles from being thrown to the outside of the chute from the inside under the effect of the centrifugal force, lighter particles can cross the lateral vertical surfaces of the steps easily to be thrown to the outside of the chute from the inside, and accordingly the yield of the heavy ore particles is high. In addition, the chute has a simple structure.
